HOUSE VENTILATING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 606,417, dated June 28, 1898.

Application filed June 26,1897.

To all whom z'tmay concern.-

Be it known that I, THOMAS HYDE, a citispecification.

My invention relates to systems for venti lating the apartments of a building by means of the pipes leading from the washbowls, bathtubs, closets, and other connections with the drain, causing a circulation from the room in which the washbowls, closets, &c., are placed through the pipes connected with said washbowls, closets, &c.; and the object of my in vention is to provide a ventilating system which shall not only prevent the escape of gases from thedrains and sewers into the apartment within which a washbowl, bathtub, or closet is placed, but which will also cause the escape of foul air from said apartments through the pipes connected with the drain. I attain this object by means of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a section of abuilding, showing the connections of the pipes with various washbowls, sinks, bath-tubs, and closets placed within apartments in a house and one method of connecting up the same to cause a circulation of air from the apartments to the exterior of the house. Fig. 2 is a section of a trap, and Fig. 3 is a section. of a valve.

Similar letters refer tosimilar parts throu ghout the several views.

It is a well-known fact that much incon venience' and many dangerous diseases result from the poisonous gases escaping from sewers and drain-pipes into the living-rooms of dwellings and other buildings, and in endeavoring to avoid these deleterious results many devices have been producedin which iinproved traps are employed to accomplish the desired result in the building. There is a danger, however, that the most perfect trap may become emptied of its sealing-water because of a partial vacuum occurring in the drain or sewer or because of evaporation of the same, leakage, or other defects, allowing the gases to escape through the trap into the Serial No. 642,395.

, house, to the great danger of its inhabitants.

of the house, preventing the possibility of the escape of gases from the sewer or drain into the apartments of the building.

In the drawings, A represents a drainpipe Within a building B, which is preferably trapped at (J from the drain D and provided with a valve J, to which is connected a freshair-carrying pipe E, having an opening e out side of the building. A with a pipe a,whioh extends upward through a'chimney F, preferably extending to the top of the chimney, allowing for the circulation of fresh air from the inlet 6 through the drainpipe A through the outlet (1 within the chimney F; as indicated by arrows in Fig; 1.

G represents a washbowl connected with the drainAby the pipe g. I also connect the pipe g with the pipe H, which passes into the chimney F and preferably extends to the top of the chimney. Within the pipe .9 and between the drain and the pipe H, as at h, I preferably place a valve J, said valve provided-with a valve-disk j, pivoted at one end, as at j, within the valve-casing and having at the end near the pivot aweight 7r, tending to hold the valve closed. The valve-disk j is adapted to open in one direction only, as shown by dotted lines in Fig. 3, it being prevented from opening in the opposite direction by means of the stop As placed in position within the pipe g the valve opens downward, allowing for the escape of the contents of the pipeg into the drain A, but preventing the passage of the contents of the pipe A into the pipe g.

1 do not limit myself to the use of a valve within the pipe g, since it is placed there to individualize each portion of the system. The trap K (shown in Fig. 2) may be substituted for the valve J, or a different trap or diiterent valve may be placed therein, or valve I also connect the drain pipe L, extending into the chimney F, and at Z with a valve J.

M represents a closet connected with the drain by the pipe m and having a pipe M extending into the chimney and the valve J placed between the pipe M and the drain A.

N represents a sink, with its pipe 07. connected with the drain A, the pipe N connected therewith and extending into the chimney F, the valve J placed in said pipe at.

0 represents stationary tubs connected With the pipe 0, leading to the drain A, and the pipe 0, extending into the chimney F, the pipe 0 provided with the valve .I.

P represents a closet having a pipe 9 connected with the drain A, provided with a valve .I and connected with the pipe P, leading into the chimney F.

In each of these fixtures there is a pipe extending into the chimney connected with the discharge-pipe from the fixture between the fixture and the drain-pipe. The pipes in the chimney F extend to the top of the chimney preferably, thus communicating with the exterior of the house. A draft is thus maintained through the pipes in the chimney, causing a suction upon the pipes connected with the fixtures, occasioning the withdrawal of air from the apartments within which the fixtures are located.

Vhen there is'a fire within the range or other apparatus (not shown in the drawings) connected with the chimney, there will be caused a rarefaction of the air within the pipes in the chimney, which will accelerate the current of air through the pipes and assist in the ventilation of the rooms; but under any circumstance, whether there is a fire connected with the chimney or not, there will be a ,circulation of air from the apartments through the pipes in the chimney. I therefore do not limit myself to the use of a chimney connected with stoves or other heating apparatus, as any flue would answer all purposes.

I am aware that heretofore a fresh-air pipe placed outside of a building was connected with the drain Within the structure, having for its object the introduction of fresh air into the drain within the house.

I am also aware thatrheretofore the discharge-pipes from water-closets and urinals have been connected with a flue but in all of the devices heretofore used and all systems heretofore employed with which I am familiar there has been no provision made for passing fresh air through the drain into the house, carrying the same directly from the drain through a pipe in a flue, nor have any of the devices or systems with which I am familiar provided for connecting the discharge-pipes from the closets and other fixtures with pipes in a flue in such a manner that traps may be omitted and the escape of gas prevented from the drains.

lVhat I claim as my invention, and desire to secure by Letters Patent, is

A system for ventilating apartments in a building, consisting of a drain,afresh-air inlet connected therewith, an air-escape pipe connected with said drain, a chimney through which said air-escape pipe extends, the discharge-pipes from the plumbing-fixtures in said building connected with said drain, pipes located in said chimney connecting respectively with said discharge-pipes, in each of said discharge-pipes, between the drain and the.

pipes connected with said discharge-pipes extending into said fine, a means for preventing passage of air or gas from the drain through the discharge-pipes, substantially as described.
